If she is willing to let you try, I say you have to do it! My wife will not let me, you are one of the lucky ones, dont let this opportunity pass you by
Explain this to her. Maybe even request she ties you up and doesn't let you out until you do what you know you need to do.
Thanks for the suggestions and support. She rolled off of me last night to go get cleaned up. I did not say anything to stop her.
